Q & A for the petulant children.
Q) I spent money to get this prize a couple months ago, why is it so easy to get for free players now?
A) Obviously Gree effed up on this one. They admitted it. If you reverse the prizes, the coupe would have been level 10 prize, which non-gold players wouldn't be likely to reach. Gree is the one that suffers most from this. What should have been a great incentive to scoop up some cash from people who missed the modifier before, is nothing more than a wasted opportunity for them.
Q) Why can't you stack two of the same item, it's not fair!
A) It's a free item you can earn with relatively little time or XP, thanks to Gree's error. You'd probably complete five levels of the LTQ anyway to get it, so quit crying.
It's pretty obvious by the number of free players who think they won the lottery on this one, that the event is actually a non-event. Here is the reality that will soon burst your bubble: Stat inflation will go up by about 10-15k, so you aren't actually getting stronger, since all your enemies are too.
Like many others, I'll go ahead and complete Level 5, then spend a rare weekend enjoying real-life.
